Auburn Hills, MI — Rigaku Innovative Tech - nologies (RIT) has launched a program to clean and recoat old synchrotron optics, either retasking them for new applications, or to refurbish and repair them for continued use. The process offers a less costly alternative to the purchasing of new optics. Along with refurbished products, the com- pany offers new optics and coating for synchrotron applications. Synchrotron beamline end stations and ana-
lytical instruments most often operate with high- intensity X-rays. Such high-intensity beams can result in damage to single film and multilayer coatings. Because synchrotron and similar custom- made optics typically require extremely precise coatings on premium quality substrates, these substrates and coatings can be very expensive and require long lead times. Optical refurbishment is an effective and effi-
cient solution to address the major challenges experienced in synchro- tron applications. The process pro- vides recovery of optical performance by removing the damaged multilayer or single film and re-depositing a new coating, removal of contami- nants without damaging the underly- ing multilayer structure, and preser- vation of the original high-quality substrate surface without the need for re-polishing. The process allows for maintenance of low micro rough- ness on any scale, from low spatial frequency roughness to high spatial

Evaluation Kit New Albany, IN — Engineers con- stantly face challenges routing multi- gigabit transceivers (MGTs). The new Avnet Zynq Transceiver Evaluation Kit (AZTEK) provides a low-cost refer- ence design that streamlines the eval- uation of FPGA SoC MGTs that require transmission of large amounts of data at high communication rates or over long distances. The AZTEK kit uses Samtec’s

frequency roughness. RIT’s process can restore some damage to high spatial frequency roughness. If the optic is too damaged in any roughness scale,

mechanical re-polishing may still be required. RIT also manufactures new synchrotron
optics, with high reflectivity and high precision coatings available on mirrors up to 1.5m (4.9 ft) long. These coatings can be single film, bi-material or tri-material multilayers, with protective top coats and adhesion layers available. The company can produce optics with coatings in narrow stripes to allow multiple material systems, as well as mul- tiple d-spacing films coated on the same optic. In addition, the company produces double multilayer monochromators on optics up to 1.5m (4.9 ft) long. In these applications, substrates such as Si (111) and other natural crystals can form one stripe of
the monochromator. Contact: Rigaku Innovative Technologies,
